Multiple imputation is rapidly becoming a popular method for handling missing data, especially with easy-to-use software like PROC MI. In this paper, however, I argue that maximum likelihood is usually better than multiple imputation for several important reasons. I then demonstrate how maximum likelihood for missing data can readily be implemented with the following SAS procedures: MI, MIXED, ...

background: human enteroviruses (evs) may have a role as a possible risk factor in the pathogenesis of mi. the aim of this study was to evaluate the presence of enterovirus genomic rna in peripheral blood samples of patients with acute myocardial infarction (mi). methods: we investigated the presence of enterovirus genomic rna in the peripheral blood of 115 patients with acute mi hospitalized i...

myocardial infarction (mi) is one of the most important health burdens worldwide. aspirin as an non- steroid anti—inflammatory drug, has been proven to be a protective factor to decrease the incidence, however its effect of mi size is still unknown. we designed this study to compare the biomarkers after mi in patients with and without aspirin intake. 378 patients were enrolled and the results s...

to evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (mi) in sheep, acute mi was induced by ligation of left anterior descending coronary artery (lad). for this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group i, thoracotomy without mi) and the experimental group (group ii, with m...
